Total dissolved solids ( TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular ( colloidal sol) suspended form. TDS are often measured in parts per million (ppm). TDS in water can be measured using a digital meter.
Tax deduction at source (TDS) is an Indian withholding tax that is a means of collecting tax on income, dividends, or asset sales by requiring the payer (or legal intermediary) to deduct tax due before paying the balance to the payee (and the tax to the revenue authority). Under the Indian Income Tax Act of 1961, income tax must be deducted at ...
The Tandy Pocket Computer or TRS-80 Pocket Computer is a line of pocket computers sold by Tandy Corporation under the Tandy or Radio Shack TRS-80 brands. Although named after the TRS-80 line of computers, they were not compatible with any TRS-80 desktop computer and did not use the Z80 CPU. Models in the Pocket Computer line were actually ...
In physics, terahertz time-domain spectroscopy ( THz-TDS) is a spectroscopic technique in which the properties of matter are probed with short pulses of terahertz radiation. The generation and detection scheme is sensitive to the sample's effect on both the amplitude and the phase of the terahertz radiation. Fourier transform of the above pulse.
The law was actually the last of the laws to be formulated. First law of thermodynamics. d U = δ Q − δ W {\displaystyle dU=\delta Q-\delta W} where. d U {\displaystyle dU} is the infinitesimal increase in internal energy of the system, δ Q {\displaystyle \delta Q} is the infinitesimal heat flow into the system, and.
Computational chemistry. Computational chemistry is a branch of chemistry that uses computer simulations to assist in solving chemical problems. [1] It uses methods of theoretical chemistry incorporated into computer programs to calculate the structures and properties of molecules, groups of molecules, and solids. [2]
Conductivity (electrolytic) Conductivity or specific conductance of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is siemens per meter (S/m). Conductivity measurements are used routinely in many industrial and environmental applications as a fast, inexpensive and reliable way of ...
Electrodialysis ( ED) is used to transport salt ions from one solution through ion-exchange membranes to another solution under the influence of an applied electric potential difference. This is done in a configuration called an electrodialysis cell. The cell consists of a feed (dilute) compartment and a concentrate ( brine) compartment formed ...
